MX51 2.775V TFT LCD supply

I have a question on the power rail voltage that serves the MX51 mcu. It's about the NVCC_IPUx pin (2V775_BOOT in the MX51EVK)... You see the TFT LCD that we are using right now has an operating voltage of 2.7 to 3.3V, and i'm worried that the 2.775V is on the edge.

Is this safe? If not, can I ask for some suggestion/s on how to ensure that the LCD supply is within "safe" range?

it's base on your power ripple voltage.if your ripple is under 75mv.i  think it isn't problem.
